I'm new to Spring Roo as well as Maven. I was trying to setup a basic Google App Engine web application using Spring Roo. But when I run the tests - perform tests/mvn test - I get an error saying unable to run the goal Unpack due to API incomatibility.
Details: gae.version: 1.6.1 gae-runtime: 0.9.2
Tried the same with 1.6.0 and 0.9.0 - still gives me the same error.
Exception:
[INFO] --- maven-gae-plugin:0.9.2:unpack (default) @ project_x ---

I tried googling this issue, but didn't come across anyone facing this issue. I guess, I'm missing some dependency in the generated POM - but due to my inexperience I'm not able to figure out the exact cause.
Let me know, if I need to upload the generated pom.xml or any other details.
meanwhile, I'll continue to figure out what is causing the issue.
Thanks in advance.
